PLOW.

SPECIFICATION forming part of Letters Patent No. 739,092, dated September 15, 1903. Application filed January 12, 1903. Serial No. 138,758. (No model.)

To all whom it may concern:

' Be it known that I, JOHN WV. LEE, a citizen of the United States, residing at Athens, in the county of Clarke and State of Georgia,

have invented certain newand useful Improvements in Flows; and I do hereby de: clare the following to be a full, clear, and

exact description of the invention, such as .struction clearly and fully set forth in the annexed specification and drawings.

In the drawings, Figure 1- is a perspective view of my improved means of adjustment applied to a plow. Fig. 2 is a front sectional view of my improved construction. Fig. 3is a side sectional View of the same. Fig. 4 is an enlarged view of a portion of the threaded bolt and the detachable collar, showing a means for securing it to said bolt.

In the drawings like letters of reference represent similar parts.

A in the drawings represents an ordinary plow-beam provided with the handles A A.

B B are two like metal plates comprising the plow-standard, to which the plow-point B is attached by the ordinary means. B B are pivotally mounted on the'plow-beam A by means of the bolt 0 and are each provided with a forwardly-extending portion 1) and an upward extension I). The upper ends of b b are connected by a cross-piece D,providedwith downward extensions (l d, which are pivoted to b b, respectively, at E E, the ends of b I) being rounded to permit the part D to move forwardly and rearwardly on E E, which is necessary in the operation.

In the middle of the cross-piece D is a circular screw-threaded opening adaptedto receive a correspondingly threaded bolt F, which is provided attits upper end with a square or other suitably-shaped head f.

G is a metal plate fastened by suitable means g g to the plow-beam A and is pro= vided with a circular recessed portion 9 of suitable size, and preferably a metal plate H of suitable size and shape is placed between the plate G and the upper side of the plowbeam A or else set into the plow-beam, as shown in the drawings, to protect said plow beam from the wear of the collar f. This plate H, which is provided with a depression h to allow for the movement of the collar f when thedevice is in operation, is preferably secured in position by the screws g 9 which fasten the plate G to the plow-beam. In the center of g is a circular or oval-shaped opening g preferably oval, to allow for the motion of F when the device is operated and of suitable size to admit the lower end of threadbolt F, which is retained in position by means of a circular collar f,provided with a rounded base, and a pin f by which it is fastened to the lower end of F. This collar f is of suitable size to loosely occupy the recess g. Thus by means of this construction the lower end of F is held rigidly to the plow-beam A, but by means of such a socket as will permit F to be turnedeither to the right or left.

From the foregoing description it is obvi ous that the operation of my device is as follows: As the bolt F is turned in its socket either to the right or left the cross-piece D must take a correspondingly higher or lower position on the bolt F, since by the specification F is screwed through D and is rotatably secured to the plow-beam A and as D is fastened to the plow-standard B B the said standard B B must consequently rise and fall in accordance with the movement of D,which, of course, will accomplish the desired result of regulating the depth of the furrow at will and with great case.

It is obvious that the details of my construcv tion may be considerably modified without departing from the spirit of my invention.

What I claim, and desire to secure by Letters Patent, is-

1. In a plow of the kind described, the combination with the beam, of a plow-standard having its upper portion divided in two parts, one on each side of the beam, the said parts being pivoted to the beam and having forwardly-extending portions, of a cross-piece connecting said extending portions above the beam, the said connecting-piece being provided with a threaded aperture and a screw revolubly connected to said beam and passing through said aperture, substantially as described.

2. I11 a plow of the class designated, the combination of a plow-standard provided with upwardly-extending portions, a cross-piece pivoted to said portions, a threaded opening in said cross-piece, a correspondingly-threaded bolt passing through said opening, said threaded bolt being provided at its upper end with a suitable head and at its lower end with a detachable collar, a plate provided with a recessed portion adapted to receive said collar and opening in said recessed portion to admit said bolt and means whereby said plate is secured to the plow-beam, substantially as described.

3. In a plow of the class designated, the combination of a plow-standard provided with upwardly-extending portions, a cross-piece pivoted to said portions, said cross-piece being provided with a threaded opening, a correspondingly-threaded bolt passing through said opening, said threaded bolt being provided at its upper end with a suitable head and at its lower end with a detachable collar, a plate provided with a recessed portion adapted to receive said collar, said recessed portion being provided with an opening adapted to admit said bolt, a protecting-plate between said recessed plate and said plowbeam and means for securing said plates to said plow-beam, substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.
